When PTFE needs to be bonded to another surface, etching process will be used to create a lamination of the liner surface for a quick and easy bonding.
Etching uses a mixture of Sodium naphthalene that is formulated to produce a bondable surface quickly and efficiently. Sodium naphthalene etching services meet surface treatments of all fluoropolymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF and ECTFE. The process can be accomplished on one or more surfaces or selectively within close tolerances.
